SPECIFICATION forming part of Letters Patent No..273,966, dated March 13, 1883.

Application filed Ilecember 9, 1881. (No model.) i

To all whom it may concern:

Be it known that I, J. S. CORBIN, a citizen of the United States of America, residing at Gouverneur,in the county of St. Lawrence and State of New York, haveinvented certain new and useful Improvements in Disk-Harrows; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled inthe art to which it appertains, to make and use the same, reference being bad to the accompanying drawings, and to letters 'or figures of reference marked thereon, which form a part of this specification.

Figure l is a bottom view of my improved barrow. Fig. 2 is a rear view. Fig. 3 is a bottoin view of one of the vibrating carrierarms, having the angular socket-iron attached. Fig. 4. is a perspective view of the locking capplate of the angular socket. Fig. 5 is a perspective view of the stirrup-hanger, having a part of each boxing removed. Fig. 6 is a reverse view of one of theremoved parts of the boxing. Fig. 7 is a section of one of the axles and its attached disks. Figs. 8 and 9 are detached views, showing the manner of connecting the disks with the axles. Fig. 10 is a perspective view of one of the slotted carrier-arm bearings. Fig. llisa top view of a portion of the main axle and its attached carrier-arms and other devices. Fig. 12 is a side view of so much of the harrow as illustrates the method of converting it into a straddle-row cornbultivator. Fig. 13 is a sectional view, enlarged, of a gang, showing the construction of the bearings. Fig. 14 is a perspective view of my barrow, taken from the rear, the disks being inclined to the line of draft.

In the drawings, A is the tongue, provided at its rear end with a lilting-handle, a, secured thereto preferably by means of a joint-bolt passing centrally through the handle and into the rear end of the tongue, where it engages with a hidden nut.

B is a cross-bar, round in cross-section, and attached to the tongue by means of a staple or eyebolt, b, about midway of its length.

0 isa seat-sprin g, supported upon the tongue by means of a cast-metal socket, c, at its lower end.

D D are braces bolted at their forward ends to the tongue, and extending rearwardly and outwardly a short distance beyond the bar B and below said bar, and connected by means to which it is secured bya nut, as shown plainly in Fig. 11.

There are two carrier-arms, GH, upon each side of the tongue, these carrier-arms being duplicates and each secured to the bar B by means of a metal bearing, Z, having grooved parts 18, which are bolted to the carrier-arms and form therewith hearings in which the bar Bis seated. upon its end face to form part of the bearing for the bar B 5 but, when preferred, such hearing may be formed entirely in the metal portion. Each of these hearings Z is provided As shown, each carrier is grooved with a slot, z,(see Figs. 1,2, 10, 12,) fora purpose which will soon be explained.

I I are equalizing-bars, one for each pair of carrier-arms, each bar beingprovided with a central opening, through which the rear end of a brace, D, passes, the ends of the bars being supported in eyebolts or loops i, which depend from carrier-arms G H. Thus it will be seen that while these carrier-arms are free to vibrate about the bar B the weight of the tongue, the bar, the drivers seat, and the driver is transferred to the carrier-arms, and thence to the axles and disks, which are connected to y the carrier-arms by devices which I will now proceed to describe.

Referring particularly to Figs. 2, 3, 4, 12, J K is an angular socket-iron, bolted firmly to the rear end of carrier-arm G, and provided with sunken circular recesses or sides j is, each provided with a semicircular overhanging rib. (See Fig. 3.) L, Fig. 4., is an angular capplate, provided with semicircular arms I, adapted to fit into recesses 2 in the bearing JK and to be secured thereto by means of a bolt passing through an opening, 4, intoa threaded hole, 5, whereby there is formed an inclosed bearing adapted to receive the circular head ICO 9 eaaecc m of a stirrup-hanger, Figs. '2 and 5, and it will be readily understood that said head m can be introduced into either of the sockets j k, the angular cap L being first removed, and can be firmly secured in position by bolting down the angular cap, after which the stirrup, though heldfirrnly in place, can be rotated, but cannot be withdrawn from its seat. The iron hearing, which is attached to the rear of arm H, is substantially like the one shown in Fig. 3, except that the circular portion of the part J is dispensed with, as shown in Fig. 2. The cap, which secures the stirrup-head m in place, is correspondingly shaped, (see also Fig.

2,) it being intended that the stirrup shall. be supported only in a position at right angles to the carrier-arm H as engaged in Figs. 1 and 2, while by the use of the construction of an gular bearing attached to carrier-arm G the stirrup can be supported either in a position at right angles to said arm or suhstautiallyin a line with said arm. (See Fig. 12.)

Referring particularly to Figs. 5, 6, 7, 8, 9, M is a stirrup-hanger, each leg of which is provided at its lower end with elongated bearings N O, the parts N being cast in the same piece with the yoke portion M, the parts 0 being castseparately and provided with lugs 0,which take into loops a, cast on the parts N, and with upwardly-extending arms 7, which are secured in place .bymean's of bolts passing through them and through bolt-holes 8 in the stirrup-hanger. ThepartsNhave each oil-holes 16. As shownin Figs. 1 and 2, the bolts which secure these parts 0 to the parts N are formed at the ends of shifting-levers B R, each lever being formed of a rod doubled at the center to form arms which straddlethe central disk of each gang, and are provided with nuts 14. The doubled end of each rod is turned down at about a right angle to the other portion of the lever, and is supported in a slot, 2, of the carrier-arm bearing Z, Figs, 1, 10, and 12.

Returning again to Figs. 5, 6, 7, 8, 9, Q, is

the gang-axle, having acentral hub or boss, 9,

and flange 20, and two flanges, one at each end, which areof a little less diameter than the diameter of the hub 9. This axle has also projecting screw-threaded ends, which may be either cast in one piece with the axle, as are the hub and flangestha-t is, they may be made of wrought-iron and inserted in the mold, so that the axle shall be cast upon them; or the axles may be made with ascrew-threaded socket in each end and a bolt or securing-screw screwed therein, instead of the projecting bolt and nut 15, as shown in the drawings. The hub 9 has upon opposite sides studs 10.

11 is a collar of such size as to pass readily over the hub 9, and provided with interior semicircular spiral ribs 12, having spaces between their ends to permit them to pass over the spurs 10. Thecenterdiskhasaholeinitscenterlarge enough to pass over hub 9, and two notches, which permit it to pass the spurs l0 and rest against the flange 20. Collar 11 is then slipped over spurs 10 against the convex face of the disk, and then rotated until by contact of the ribs 11 with spurs 10 the disk is firmly clamped between said collar and flange. 20, as will be readily understood without further explanation; A pin, 17, is then driven through a hole made in the disk, one side of the hole corresponding with the notch 22, Fig. 8, and by preference a corresponding notch in the periphery of the flange 20, whereby the disk and collar 11 are firmly locked to the axle. The outer disks are now slipped over the ends of the axle against flanges 21 and secured by nuts 15, or by bolts which enter the ends of the axle, as has been explained. The axle is then placed in the bearings N O, lateral movement of the axle being prevented' by contact of the hub 9 and flanges 20 21 with the ends of the elongated bearings. I am'aware that a gang-axle has been supported against lateral movement or endwise thrust by means of a flange or collar fixed upon said axle and engaging with a groove formed forits reception'in the hearing; but my construction possesses many advantages over any prior one of which I have knowledge, because I am enabled to use the hubs or flanges against which the disks are clamped to prevent endwise thrust; and, further, when it is desired to use anti-friction balls, it is much easier to construct these hearings with suitable chambers and to introduce balls into them than it would be if such chambers were located within the bearings, as will be seen by a description to be hereinafter given.

U, carrying a rose plate, X, upon a stud, w,

projecting rearwardiy from a bearing-plate, V, which is mounted upon the rear end'of the tongue. Thatportion of this plate which abuts against thetongue is provided with projecting flanges or lips, which form a rectangular socket, which receives the end of the tongue, and thus prevents the plate from turning, said plate being clamped to the tongue by thesame bolt which passes through the handle a, as has been explained.

The pivot 00 is surrounded by a rose plate, Y, a spring, '1 surrounding the pivot and holding the rose-plate in close contact, so that the lever U is held firmly in such position as it may be placed, the spring U permitting roseplate X to yield when the lever is forcibly moved.

The downward extension 11. of lever U is pivoted to a link, T. This link T is pivoted to the part u of the hand-lever, and runs thence to the outer lever, B, passing through the loop '1 of said outer lever, and returning thence to the loop 1" of the inner lever, It, thus forming Mast c a i a tie-bar, S, and insuring that whenthe position of i one of the gangs is changed a corresponding change in the position of the other gang shall be effected. 7

Referring to Fig. 2, 19 is a link connecting lever U with lever W, which is pivoted at w to the bearing-plate V, said lever W being connected to the disk gangs on that side of the tongue by means of a corresponding set oflevets and links, Wherebythe position of all the gangs may be shifted simultaneously by the.

. driver while riding on the barrow, the rose- B by means of clamps b" and braces D, the rear end of the braces being shifted so as to plates X Y holding the gangs in the position to which they have been thus shifted. I

Vhen it is desired to convert the harrow into a straddle-row cultivator,Iremove the outer pair of disks, the equalizing-bars, the shiftinglevers, links, and saddles, and move the inner carrier-arms, Gr, outward and move them into a vertical position, fastening them to the bar take into eyes 9. I also remove the stirruphangers from the sockets 7t and put them into the sockets tightening up the plate L, so as to hold them at such angle relative to the line of draft as maybe desired. (See Fig. 12.) The seat may also be removed, if desired, the bandle a facilitatingthe guidingof the cultivator by the driver if it be found necessary.

It will be seen that each stirrup-hanger constitutes a gang-frame in which the gang is mounted, and which is capable of being oscillatedrelative to its carrier-arm by means of the lever and links.

It will'also be seen that each axle is cast with supporting-flangesone for each diskand that the disks are placed onthe axle solely by means of these permanently attached flanges.

In Fig. 13 the axle Q is supported upon antifriction balls 0 which are seated in, annular recesses formed by the flanges m, which project from and are cast with or upon the tubular hearings or boxes at the lower ends of the arms of the stirrup-hanger M. By an examination of this figure it will be seen that these anti-friction balls not only engage with the axle to prevent friction of said axle upon the inner walls of the tubular supports, but also engage with the hub 9 and flanges 20 21, thus to prevent undue longitudinal movement of the axle relative to the elongated tubular supports. Thus these anti-friction balls support the axle against the longitudinal thrust which is produced by the engagement of the disks with the ground which is being pulverized,-as will be readily understood without further explanation.

It will be understood that the foot-board A may be used as a seat when the implement is converted into a straddle-row cultivator, as shown in Fig. 12.

I do not in this case claim any inventions except those which are specifically recited in the claims hereof, reserving to myself the right to claim any other patentable features, which 1.
